I'm trying to deploy a simple restful service in JBoss EAP 6.2 with Jersey 2.19.

Subclass of Application class:

package com.jersey.mywebapp;

import javax.ws.rs.ApplicationPath;

import javax.ws.rs.core.Application;

import java.util.HashSet;

import java.util.Set;

@ApplicationPath("resources")

public class MyApp extends Application {

    public Set<Class<?>> getClasses() {

        Set<Class<?>> s = new HashSet<Class<?>>();

        s.add(MyResource.class);

        return s;

    }

}

RS Implementation class:

package com.jersey.mywebapp;

import javax.ws.rs.GET;

import javax.ws.rs.Path;

import javax.ws.rs.Produces;

import javax.ws.rs.core.MediaType;

@Path("myresource")

public class MyResource {

    @GET

    @Produces(MediaType.TEXT_PLAIN)

    public String getIt() {

        return "Got it!";

    }

}

My deployment descriptor:

..

    <servlet>

        <display-name>My JAX-RS Servlet</display-name>

        <servlet-name>com.jersey.mywebapp.MyApp</servlet-name>

        <init-param>

            <param-name>javax.ws.rs.Application</param-name>

            <param-value>com.jersey.mywebapp.MyApp</param-value>

        </init-param>

    </servlet>

    <servlet-mapping>

        <servlet-name>com.jersey.mywebapp.MyApp</servlet-name>

        <url-pattern>/resources/*</url-pattern>

    </servlet-mapping>

...

Getting the below error while accessing the resource (localhost:8080/{context}/resources/myresource

As per my understanding JBoss EAP 6.2 supports Servlet 3.0 and as per Jersey documentation (Chapter 4. Application Deployment and Runtime Environments), Its valid to omit the servlet-class as per servlet pluggability mechanism.

Please advise on how to resolve this problem?

Note: To avoid/suppress RESTEasy from scanning for JAX RS resources i have commented out - <subsystem xmlns="urn:jboss:domain:jaxrs:1.0"/> from standalone.xml
